+AND "not httpRoute.enabled" IS PART OF THAT GATE RATHER THAN REDUNDANT WITH
+IT. Without it this block's per-entry required() can fire while BOTH modes are
+on, and then the render reports "mtaSts.hosts[0] has no tlsSecretName, and in
+Ingress mode every entry needs one" - true, and the wrong diagnosis: the

+claim about a configuration that is not coherent at all. Whoever met it would
+add a tlsSecretName, re-run, and reach the real message one round later, or
+conclude this feature was the problem. MEASURED on this chart before the gate
+was added, not reasoned about.

+Ordering is not the fix and could not be: Helm renders templates in an order a
+chart cannot pin, so this template may not assume the httproute template's
+structural abort runs first. SCOPE is the fix - with both modes on this block
+validates nothing, so the only fail left is the one that names the real
+problem. The generalisation (a specific validation must not be reachable in a
+state a structural validation already rejects) is the Lessons-Learned entry
